Question

please help!! what is the m<4?

Answer 1

Answer:

$m\angle 4 = 117\textdegree$

Step-by-step explanation:

-Both $\angle 1$and $\angle 4$ are supplementary, which they both equal to $180\textdegree$. So, to get the measurement of $\angle 4$, you need to subtract measure of $\angle 1$, from $180\textdegree$ :

-Both $\angle 1$ and $\angle 4$ are supplementary:

$\angle 1 + \angle 4 = 180\textdegree$

-Find the $m \angle 4$ by subtracting the $m \angle 1$ from $180$ :

$180\textdegree - 63\textdegree = 117\textdegree$

So, the $m\angle 4$ is $117\textdegree$ .
